As the population ages, the spaces we live in play a critical role in how we age.
Florida State University’s Daejin Kim, associate professor in the Department of Interior Architecture and Design, is a nationally recognized expert in health care design and environmental psychology. His research focuses on how interior design can support aging in place, improve well-being and preserve dignity for older adults.
With academic training in South Korea and the United States, Kim brings a global perspective to his work, which includes award-winning publications and a seat on the board of the Journal of Interior Design. His insights help shape homes, hospitals and communities into environments that promote independence and comfort.
What makes a home easier to live in as we get older?
There is no one-size-fits-all solution. Because older adults inevitably experience physical, psychological and social changes, a home should be designed to support those changing needs over time. This means creating home environments that are flexible and resilient — able to be easily modified as needs evolve. Most importantly, thoughtful design respects both independence and dignity, helping older adults feel safe, connected and empowered — without being labeled by age.
How can small design changes make a big difference for seniors?
Small design changes can have a profound impact because they address the everyday challenges older adults face. Simple adjustments such as adding night lights to improve navigation or using contrasting colors for better visibility, not only enhance comfort but also reduce the risk of falling and ease the fear of falling, which is critical for maintaining confidence and independence. Even modest modifications, when thoughtfully tailored, can make daily life easier, safer and more empowering.
What are the biggest design mistakes people make when planning for aging?
A common mistake today is treating safety as the only goal. While safety features such as a grab bar are vital, they can sometimes carry a stigma of aging or disability if they are added without sensitivity, making the home feel clinical instead of supportive. Design should ensure safety while also protecting the dignity, comfort and identity of older residents. Especially, by understanding how older adults interact with their environment over time, designers can integrate supportive features in ways that feel natural, discreet and home-like — so safety enhances independence rather than labeling it.
How can hospitals or clinics feel more comfortable for older patients?
Hospitals and clinics can feel more comfortable when they resemble the warmth of home rather than an institution. This means using natural and warm temperature light, softer finishes and familiar furniture arrangements that feel less clinical. Just as important, spaces should support older adults’ psychological and social needs — family visiting areas that encourage connection, and communal lounges that reduce loneliness. By combining safety with a welcoming, home-like atmosphere, health care settings can promote dignity, healing and a sense of belonging.
What can designers learn from how older adults actually use space every day?
Designers learn the most by observing how older adults interact with the physical environment based on their different needs. As people age, they face various challenges such as mobility limitations, vision changes, or cognitive impairments, — and each requires different forms of support. By understanding how the home environment can respond to these unique and specific demands, designers can move beyond generic solutions and create spaces that are flexible, dignified and truly supportive of daily life.
